RE: the whisker biscuit
Absolutely love the whisker biscuit. I've had it on both of my bows. Currently have it on my mathews switchback. They are flawless once tuned correctly. I love to have it for walking to and from my stand sights. I put a little piece of mole skin on the bottom of the insert where the arrow rests for a completely stealth draw back. I use an alluminum insert (wider hole) with carbon arrows. The larger hole allows room for the mole skin and perfect clearance. The mole skin strip I use is about 4 inches long and I center it inside the biscuit hole and wrap it around the edges. Deer won't even know you're there.
